Finology Ventures Interview Questions and Answers

Earthing is provided at the base of the MSGL reactor.

• Earthing is necessary to prevent electrical hazards and ensure safety.

• The earthing system consists of copper rods or plates buried in the ground.

• The earthing system is connected to the reactor through a copper conductor.

• The earthing system should have low resistance to ensure effective grounding.

• Earthing is also provided for other equipment associated with the reactor, such as transformers and switchgear.

I have handled solvents like methanol, toluene, and acetonitrile with flash points ranging from -14°C to 44°C.

• Methanol has a flash point of -14°C

• Toluene has a flash point of 4°C

• Acetonitrile has a flash point of 44°C

• Flash point is the temperature at which a solvent gives off enough vapor to ignite in air

Syphon type pressure gauges are used in steam lines to protect the gauge from high temperatures and prevent damage.

• Syphon type pressure gauges protect the gauge from high temperatures in steam lines

• They prevent direct contact of the gauge with steam, which can cause damage

• Syphons also help to cool down the steam before it reaches the gauge, ensuring accurate readings

LD 50 or LC 50 is the lethal dose or concentration of a substance that kills 50% of the test population.

• LD 50 refers to the dose of a substance that is lethal to 50% of the test population

• LC 50 refers to the concentration of a substance that is lethal to 50% of the test population

• It is commonly used in toxicology to determine the toxicity of a substance

• LD 50 and LC 50 values are often used to establish safety guidelines for exposure to chemicals

• For example, the LD 50 of caffe...read more

Steam traps are devices used to discharge condensate and non-condensable gases from steam systems while preventing steam from escaping.

• There are different types of steam traps such as mechanical, thermostatic, and thermodynamic traps.

• Mechanical traps operate based on the difference in density between condensate and steam.

• Thermostatic traps use temperature-sensitive elements to open and close the trap.

• Thermodynamic traps rely on the dynamic effect of flash steam to operate.

• Ste...read more

A process flow diagram is a visual representation of the steps in a process, showing how they relate to each other.

• It outlines the sequence of tasks, decisions, and interactions involved in a process.

• It helps in identifying bottlenecks, inefficiencies, and areas for improvement.

• Common symbols used in process flow diagrams include rectangles for tasks, diamonds for decisions, and arrows for the flow of the process.

• Example: A process flow diagram for a manufacturing process wou...read more

A runaway reaction situation is when a chemical reaction becomes uncontrollable and poses a safety hazard.

• Identify the root cause of the runaway reaction

• Implement safety measures to contain the reaction

• Consult with experts or follow established protocols for handling runaway reactions
